TI C6713 DSP

Started by Lauren June 18, 2004
I have a question about the TI C6713 and C6713B DSPs. TI states that
the 225 mHz delivers 1350 Mflops and the 300 mHZ delivers 1800 Mflops.
Most places I have looked say "up to" this amount of mflops, but is
there any accepted/tested benchmark for these DSPs that gives a more
consistent result? Also what is the diffence in power consumption
between the 225 mhz and the 300 mhz ? Thanks for your help. :)
Hi
I only know you could find power consumption on the datasheet of the DSP.

Benchmark the code your want to run - many more things than raw processing affect how suitable a DSP is for an application. Lack of memory bandwidth is usally a good way to throttle an otherwise fast processor. The "up to" figure are down to the fact that the c6713 can execute 6 floating-point ops per cycle (if you happen to have the right instruction mix...)

Does this help? http://focus.ti.com/docs/apps/catalog/resources/appnoteabstract.jhtml?abstractName=spra889a Cheers, Martin -- martin.j.thompson@trw.com TRW Conekt, Solihull, UK http://www.trw.com/conekt
